' 20 Claims.

This application is filed for the purpose of claiming the divisible inventive subject matter of my co-pending application, Serial No. 100,246, filed September 11, 1936, for Machine for making purely pressed glassware, comprising novel apparatus for and methods of forming and cooling hollow glassware. application, Serial No. 100,246, of which the present application is a continuation in part, such inventive subject matter is illustrated in the drawings and described in the specification of the present application in connection with the structural and operating features of a feeder-fed forming machine operating on the narrow neck principle butprovided with suitable instrumentalities and actuating mechanisms for pressing charges of molten glass into articles of glassware and for handling such ware. The invention to be protected by this'application is independent of the specific means employed to form the charges of molten glass into articles of glassware and provides novel combinations of structural elements and cooperative steps by which charges of molten glass are formed in suitable molds into articles of hollowv glassware ,by any suitable means and in any suitable way and, arecooled. at their outer and inner surfaces by novel means and in a novel manner so as to have the requisite strength, durabilityand physical characteristics tor the use or "purpose intended. Other features and advantages of the invention will hereinafter be pointedout or will be apparent from the following description of the construction and operation or the machine shown in the accompanying drawings, in which:'

Figure 1 is a view in vertical sectional elevation 01' a portion of a narrow neck machine embodying the invention, parts being omitted for clarity in illustration; I

Fig. 2 is a similar view on enlarged scale, showing in detail the means for pressingthe ware;

Fig. 3 is a view similar to Fig. 2, but showing in detail means for'receiving, cooling and discharging the pressed ware from the machine;

Fig. 4 is a view illustrating the operation supporting and cooling an article of ware in preparation for its discharge from'the machine.

" For purposes of illustration and not in limitation of the invention, the illustrated embodiment (Fig. l) consists of the adaptation of the invention to one section or the Hartford Individual As in my aforesaid original- Section Machine, disclosed in the patent to H. W.

made to any number of sections'of such" machine.

As shown in Fig. 5 of the Ingle patent, each section of such machine comprises a blank mold and'neck pin located at the blank forming station and with which cooperate adelivery funnel, a settle blow head and a neck mold.- These and the other narrow neck forming devices are removably attached to their respective operating members for the purpose, but only for-th'epurpose, of substituting other similar devices in changing from the production of one size or style of narrow neck ware to another.

Similarly, as shown in'Fig. l herein, the base of the machine supports vertical-shaft I for holders, one of which appears at' 8 which in Ingle carry the blank mold sections. At 9 is shown what in Ingle constitutes the neck'pin operating mechanism, at H (Fig.2) In gle's funnel carrying arm (in which funnel I! of the presentinvention is removably secured by ring i3), at H an arm similar to Inglesfsettle" blow head arm and at I5 Ingles i'nvertingneck mold carrying and transfer arm. I

Each section of the machine ofthe patent also includes a blow m'old' at the finish blowing station and hence Fig. 1 herein shows the vertical shaft l6 for the blow mold-sections of such mold of the patent-(not shown), and the member ll for tilting the bottom plate (notshown) or the patent. Also shown at this station i559. finish blow head l8 and Fig. 1 shows at It the'finish blow head operating arm, both substantially "as-shown in the patent to Ingle. 9

The operation of the actuating or carrying members or the narrow neck machine'will be explained hereinafter, it being desired first to describe the utilization" of such members in the operation of pressing and'pressed ware handling devices.

Referringto Figs. 2 and 3, it will beseen that the neck mold carrying arm has removably fitted therein a sectional holder, as indicated at -2l, which carries the sections of pressing mold 22, and a solid mold bottomorclosure 23, to form a mold cavity of the shape desired, in thisins'tance for forming a threaded fuse case. 'Themold bottom 23 has a lug 24 thereon which is received in an opening 25 of the neck pin mechanism 9, whereby the latter serves to center the mold bottom and the mold 22 for registration with pressing ring 26. will be apparent from Fig. '2,

mechanism 9 serves as'a support or rest for the pressing mold during the operation or pressing.

The plunger assembly includes casing 28 removably secured in known manner in the arm I4, as by meansoi' lugs'and flanges" or" a bayonet joint, aspartlally shown, this casing containing -spring pressed plunger sleeve 29 which fits into fiunnel I2 and in which plunger carrier 3| is slidably mounted under pressure of spring 3.2 in cage 33 on the casing. The downward movement of the plunger assembly is stopped by spring 34 engaging shoulder 35, the degree of pressure applied to the plunger depending uponthe strength ofyspring 32, as will be understood.

To insure that themold sections 22 will remain closed during the pressing operation, the blank mold carryingarms 8 (Fig. 2') are employed as a, mold lockto the holders 2| for the mold sections The funnel carrying and plunger carrying arms i H and M ar os illat d. and lowered y the shaft pon which they ar mounted y ans shown n d tail in he.

Various types of pressed ware may be produced by the machine embodying this invention and changes made in the construction and operation of the several parts without departing .from the scope oi the appended claims. The design of discharge device 43 may be changed to suit different t p s of ware.

I1 desired, cooling air may be applied locally to the upper. surface of the glass article while it is being cooled externally by air from the opposed nozzles "-47 and internally by air from the member-l3. This may be conveniently done by use of blow head I 8 of the machine as hereinbefore described. Of course, such blow head must first be raised from its Fig.3 position to permit returnswinging movement-of the mold 22 toward the station at which another article of glassware istol be pressed therein.
